All [[Heal]] checks against disease are long-term care.

Each disease has a save DC, an incubation period, a number of effects, and a method of transmission.  

Each disease has a save DC, an incubation period, a number of effects, and a method of transmission. Some have more than one DC, as they might be, for example, very hard to catch but very difficult to get rid of. If in any case it is unclear what DC to use, use the lower one.

When a character is first exposed to a disease, they must make a fortitude save equal to the disease's DC. If they are aware they will be exposed to this specific disease and a heal check (DC 20) has been made in the past hour, they get a +1 on this save. If they succeed on this save, they cannot be affected by this disease for another hour.

If they are aware they will be exposed to this specific disease and a heal check (DC 20) has been made in the past hour, they get a +1 on this save. If they succeed on this save, they cannot be affected by this disease for another hour. Each hour of exposure requires a new save.

If the save is failed, they are now infected by the disease, which lays dormant for its incubation period. The character does not know that they are infected, though a successful heal check (DC disease's DC - 5) will reveal that they are infected.

If the save is failed, they are now infected by the disease, which lays dormant for its incubation period. The character does not know that they are infected, though a successful heal check (DC disease's DC - 5) will reveal that they are infected. At this point, a character may make heal checks to cure the disease, as below (beat DC by 5).
